Rebuild brake calipers? my three amigos fix hopefully
 

So i ended up finding my three amigos issue- the calipers hang and act weird at different times- this was due to mud getting into the calipers from my fun mudding adventure with Dusty1 and a few other friends.

i bought the two land rover kits and it was straight forward for the back.

Rear Caliper rebuild

1.remove banjo bolt
2.put caliper in vice
3.find brass rod or rod long enough to tap piston out
4.once the piston is out remove the outer seal
5.remove inner square seal
6.clean caliper with brake cleaner and let dry
7.install new square seal- first dab it with dot 4 brake fluid( good idea to lube up piston wall too)
8.install outer seal by putting it in front first and working down the seal to the bottom of the piston till the seal is sticking out from the bottom enough to put in the caliper grove. <- Very Important! i know as i made the mistake of not doing this and destroying a new seal.
9. press on new piston with a c clamp or whatever method you like.
10.caliper is rebuilt.
11.do it again for other side.



Front Caliper rebuild -tricky sob's and this was the method i used- use at your discretion.

1.Remove banjo bolt
2.Put caliper in vice
3.hammer out one piston with rod from earlier
4.once the piston is out remove the outer seal
5.remove inner square seal
6.grab a drink and stay calm- how do you remove the second piston?
7.destroy or carefully remove outer seal from piston(your choice) revealing a groove
8.With a flat head tap the piston out making sure force is going to the middle of the ridge as that worked best for me.
9.once the piston is out remove the outer seal- or whats left of it
10.remove inner square seal
11.clean caliper with brake cleaner and let dry
12.install new square seals- first dab it with dot 4 brake fluid( good idea to lube up piston wall too)
13.install outer seals by putting it in front first and working down the seal to the bottom of the piston till the seal is sticking out from the bottom enough to put in the caliper grove. <- Very Important!
14. press on new pistons with a c clamp or whatever method you like.
15.caliper is rebuilt.
16.do it again for other side.

once done they should look like:

except for the fact that you paid attention to how the outer seal is installed and you didnt rear yours up;)

I will take pictures when i rebuild the ones coming off the rover- i will advise if this fixed my three amigos- as it should.


Bleeding the brakes with the autocom will be cake as they will be power bled.

nice


where did you get the kit

might i suggest a different way to remove the pistons with less damage. put a 1/2 inch block of plywood in the caliper where the shoe would fit and blow air into the opening for the brake hose. the air will push the piston out of the caliper.
almost the same going back, replace all your seals, hold the piston lightly again the dust boot while slowly blowing air into the hole. this will push the dust seal out and over the edge of the piston, now you can just slide them in place.

Ah.. that sounds like fun... and note to self... NO MUD!

Just wondering what code you were getting?

ive seen it done on youtube- however they weren't budging when i tried it.

Not sure if you have an Oreillys Auto Parts in your part of the country?, but I bought these kits for around 7 bucks a piece or something...I think the rears were even cheaper?? anyway, one of my rears was sticking, and after taking it apart, the piston would bind all by itself (no seals) when you would try to slide it back and forth in the caliper bore. I took my wheel brake cylinder hone, and honed it with dot4 for a second, checked with piston, bored for another second, then wall-la, the piston smoothly slid into the bore.

This is the most affordable way to fix your brake caliper issues..By the way, my sticky rear caliper was basically brand new from the PO!! Not sure what your going to get from the parts store.....

Air pressure is the correct way to remove your pistons, but in my case, the binding piston would not come out with air, so I did what Is1morethanyou did. Be careful when beating the pistons out, they are soft metal.

Good write up Is1morethanyou

ABS code 86rear right wheel sensor - the caliper that works the best on my rover.

since the other three are partially braked they stay within spec of each other.
